Administrators at the American Indian Model Schools—a set of three Oakland charter schools, two middle schools and one high school—responded late Monday night to a 1,080-page notice of violations given to them by the Oakland Unified School District, OUSD spokesperson Troy Flint said Wednesday.

School officials had been given until November 28 to respond to the district’s allegations regarding improper business contracts, inappropriate credit card usage and lack of school board meeting documentation, but filed their response two days early. If the response does not appropriately answer the questions posed by OUSD school board members about the schools’ finances and organization, the district could decide to revoke the schools’ charters.
